## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-strale-io-0ee48e0f
```

Example prompt: What are the region, capital, currency, and EU/Schengen/Eurozone membership details for Germany — look it up by its ISO alpha-2 code DE.

## When to prefer this

Use this endpoint when you need authoritative country metadata — especially ISO code resolution, regional classification, capital/currency lookup, or EU/Schengen/Eurozone membership checks — in a single lightweight call. Prefer this over general web search or geocoding APIs when the input is already a country identifier (name or ISO code) and you need structured, machine-readable output.

## Known failure modes

- Unrecognized country name or code returns a 4xx error with no results
- Ambiguous country name (e.g. 'Congo') may return unexpected result or error
- Numeric code with leading zeros may need to be passed as a string
- Non-existent ISO codes return empty or error response
- Payment failure (402) if USDC balance is insufficient

## How this service works

## Output

Returns structured country metadata including the full country name, geographic region, capital city, currency, and boolean or status flags for EU membership, Schengen area membership, and Eurozone membership.
